The cast of the Real Housewives of New Jersey are secretly worried if they will return for the upcoming season.

According to a source, the show's stars--Teresa Giudice, Caroline Manzo, Melissa Gorga, Kathey Wakile and Jacquelien Laurita--are still waiting to learn from Bravo if they will return for season 6. A show production source said the cast mates have yet to sign a contract that confirms their return so they are beginning to "freak out" over the uncertainty.

"They're all starting to freak out," a show source told Radar Online. "The women won't get their contracts until after the reunion show for this season is filmed and that is happening the first week in September."

"They have to do everything that is required of them for THIS season and then Bravo will lock them down for the next season. But the stalemate is making everyone really nervous," the source added.

The cast members would like to follow in the same footsteps of the stars that appear in The Real Housewives Of New York and ask for salary raises but there is concern that recent legal troubles leave them uncertain if they could get a pay raise.

"With Teresa's crazy indictment and October trial coming up, the ladies know that Bravo wants them all back, but they don't know if they're going to be able to get any more money," the source said.

The cast, however, would like to sign on knowing that Giudice's legal troubles played out in season 6 could draw in bigger ratings and more viewership.

"All the ladies know that Teresa's court drama could be amazing for ratings and they all want to be a part of that and they're hoping Bravo will quickly get them all new deals so they can start filming again right away. They know that Teresa is the star and they'll have to have her back so they're hoping that they all will be back too," the source said.

Another show insider revealed in an earlier report that Giudice's recent indictment for 39 charges related to financial fraud is an opportunity the network does not want to miss.

"Shooting will start earlier than expected because producers wanted to capture what's happening with Teresa and Joe," the source told Wetpaint.

If Giudice and her husband, Joe Giudice, end up with house arrest, the network already has a plan in place to continue filming the troubled reality stars.

Giudice's attorney Henry Klingeman, told NorthJersey.com the day after she was indicted that he could not say whether she would appear on the show, but he would like for his client to continue her work with Bravo. According to the attorney, filming RHONJ is a "source of passion for her and a source of support for her kids."

Meanwhile, Manzo will get her own spinoff show and her deal has reportedly left Giudice "jealous."
